Preprints with The Lancet is a collaboration between The Lancet Group of journals and SSRN to facilitate the open sharing of preprints for early engagement, community comment, and collaboration. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early-stage research papers that have not been peer-reviewed. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. The findings should not be used for clinical or public health decision-making or presented without highlighting these facts. For more information, please see the FAQs.
Severe Pain is Associated with Critical Illness and Mortality in Hospitalised Patients Across Africa: A Point Prevalence Study of 22 African Nations
Background: Pain in hospitalised patients is common and associated with secondary complications. There is little literature describing the prevalence and severity of pain in unselected samples of hospitalised patients across Africa. The relationships between pain severity and critical illness and mortality are unknown.
Methods: This international prospective point-prevalence study in acute hospitals across Africa included all inpatients ≥18 years old. On a single day, investigators assessed patients’ worst pain in the preceding 24 hours on a 0 – 10 visual-numerical scale and vital signs. Severe pain was classified as pain ≥7/10. Patients were classified as critically ill if ≥1 vital sign(s) was out of range, according to predefined definitions. Mortality was assessed seven days later. Data are presented as mean (±SD), median [IQR], n (%) and odds ratios with 95% confidence intervals.
Findings: We included 19 438 patients from 180 hospitals across 22 African countries and territories between September and December 2023. The median [IQR] age was 40 [29; 59] years, and 10 874/19 429 (56%) patients were female. The median [IQR] pain severity was 3 [0; 5], and 2 795/19 438 (14·4%) reported severe pain. Risk-adjusted multivariable regression models showed that severe pain was independently associated with critical illness (p < 0·001) and with seven-day mortality (p = 0·020).
Interpretation: One in seven hospitalised patients across Africa reports severe acute pain. Severe pain is associated with both critical illness and mortality. Resources should be directed to effective and feasible strategies to manage acute pain and potentially impact clinical outcomes.
